DETAILED DESCRIPTION

Hereinafter, exemplary embodiments will be described more fully with reference to the accompanying drawings. The inventive concept may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In drawings, elements irrelevant to description are not shown for clear description, and like elements denote like reference numerals throughout the specification.

In the specification, when a region is “connected” to another region, the regions may not only be “directly connected”, but may also be “electrically connected” via another device therebetween. Also, when a region “includes” an element, the region may further include another element instead of excluding the other element, otherwise differently stated.

FIG. 1 is a flowchart illustrating a process of displaying data on a screen of a display apparatus according to a relative location of a mobile terminal with respect to the display apparatus, by a display apparatus, according to an exemplary embodiment.

The display apparatus 1100 performs short range wireless communication with the mobile terminal through a short range wireless communication module included in the display apparatus, in operation S100.

According to an exemplary embodiment, the display apparatus may receive information about the mobile terminal through the short range wireless communication. Here, the display apparatus may include profile information about the mobile terminal, such as a type of the mobile terminal, a size of the mobile terminal, and a shape of the mobile terminal.

According to another exemplary embodiment the display apparatus may receive information about geomagnetism detected by a geomagnetic sensor included in the mobile terminal from the mobile terminal through short range wireless communication. The information about the geomagnetism may be used to determine a direction where the mobile terminal is placed.

In the present specification, the direction of the mobile terminal is determined by using the geomagnetic sensor, but the geomagnetic sensor may be replaced by another sensor, such as a tilt sensor, to determine the direction of the mobile terminal.

Then, the display apparatus may identify the short range wireless communication module that performed the short range wireless communication with the mobile terminal, from among a plurality of short range wireless communication modules, in operation S110.

According to an embodiment, an identification may be set for each of the short range wireless communication modules. For example, identification values N1, N2, N3, and N4 may be respectively set for four short range wireless communication modules included in the display apparatus. Here, when an event of performing short range wireless communication with the mobile terminal is generated in the short range wireless communication module having the identification value of N2, the display apparatus may obtain the identification value of N2. The display apparatus may identify the short range wireless communication module that performed the short range wireless communication with the mobile terminal according to the obtained identification value.

Then, in operation S120, the display apparatus may determine a relative location of the mobile terminal with respect to the display apparatus, according to the result of identifying in operation S110.

According to an embodiment, a table for matching a coordinate value indicating a location of the mobile terminal on the screen of the display apparatus to the identification value of the short range wireless communication module may be stored in the display apparatus. For example, coordinate values (x1, y1), (x1, y2), (x2, y1), and (x2, y2) may be matched respectively to the identification values N1 through N4. When the display apparatus obtains the identification value N2 in operation S110, the display apparatus may determine that the mobile terminal is located at a location corresponding to the coordinate value (x1, y2) on the screen of the display apparatus.

Also, according to an exemplary embodiment, the relative location may denote the location of the mobile terminal on the screen of the display apparatus. For example, when short range wireless communication modules 1040 are arranged in a lattice shape on a rear portion of a screen 1300 of a display apparatus 1100 as shown in FIG. 13, the mobile terminal 1110 may be placed on the screen of the display apparatus 1100 so that the short range wireless communication module 1040 performs the short range wireless communication with the mobile terminal. Accordingly, the display apparatus may identify the short range wireless communication module that performed the short range wireless communication with the mobile terminal to determine the location of the mobile terminal on the screen of the display apparatus.

Alternatively, according to another exemplary embodiment, the relative location may denote the location of the mobile terminal within a predetermined range of a front portion of the display apparatus. For example, as shown in FIG. 18, when the short range wireless communication modules 1040 are disposed on a front portion of the display apparatus 1100, the mobile terminal may be placed within a predetermined range of the front portion of the display apparatus 1100 so that the short range wireless communication module 1040 performs short range wireless communication with the mobile terminal. Accordingly, the display apparatus may identify the short range wireless communication module that performed the short range wireless communication with the mobile terminal to determine the location of the mobile terminal on the screen of the display apparatus.

Alternatively, according to another exemplary embodiment, the display apparatus may compare information about geomagnetism that is detected by a geomagnetic sensor included in the mobile terminal and received from the mobile terminal, and information about geomagnetism detected by a geomagnetic sensor included in the display apparatus. The display apparatus may determine the direction of the mobile terminal placed on the screen of the display apparatus according to the result of comparing.

FIGS. 13 and 18 are only exemplary embodiments, and the inventive concept is not limited to structures shown in FIGS. 13 and 18.

Then, in operation S130, the display apparatus may display data according to the relative location of the mobile terminal determined in operation S120.

Here, the data may be data transmitted from the mobile terminal or data stored in a data storage unit of the display apparatus. In addition, the data may include information to be displayed on the display apparatus or the mobile terminal. For example, a photograph, a moving image, a document, or a web page may be included in the data to be displayed on the display apparatus.

According to an embodiment, the display apparatus may receive data through the short range wireless communication from the mobile terminal. For example, uniform resource locator (URL) information may be received through the short range wireless communication from the mobile terminal, and a web page may be displayed by using the received URL information.

According to another embodiment, the display apparatus may connect to the mobile terminal by using a wireless communication method other than the short range wireless communication. Then, the display apparatus may receive data from the mobile terminal by using the other wireless communication method. For example, a sub-system identification (SSID) and a password for an access point connected to the display apparatus may be transmitted to the mobile terminal via the short range wireless communication, and the mobile terminal may connect to the access point. The display apparatus may connect to the mobile terminal through the access point. Here, the access point may be included in the display apparatus.

According to an exemplary embodiment, the display apparatus may display the data while further considering information about the mobile terminal in operation S130. For example, the data may be displayed at a location on the screen away from the relative location by a predetermined distance while further considering a size of the mobile terminal.

According to another exemplary embodiment, the display apparatus may display data on the screen according to the direction of the mobile terminal determined in operation S130. For example, when the geomagnetism detected by the mobile terminal and the display apparatus is tilted by 30°, the data may be displayed in a tilted state by 30° to the right on the screen.

FIG. 2 is a flowchart illustrating a process of displaying a graphic user interface (GUI) on a screen of a display apparatus by receiving a GUI object from a mobile terminal, by the display apparatus, according to an exemplary embodiment.

According to another exemplary embodiment, as will be described with reference to FIGS. 7 and 8, the mobile terminal may be disposed within a predetermined range of the front portion of the display apparatus. A region of the GUI displayed on the screen of the display apparatus may gradually expand from the location on the screen corresponding to the location of the mobile terminal.

Then, the display apparatus may transmit a control command input through the displayed GUI to the mobile terminal, in operation S220. For example, an icon for executing an application installed in the mobile terminal may be displayed on the display apparatus. When a user selects the icon displayed on the display apparatus, the display apparatus may transmit an application execution command to the mobile terminal.

FIG. 3 is a flowchart illustrating a process of connecting to a mobile terminal in a communication method other than short range wireless communication and displaying a list about data stored in the mobile terminal, by a display apparatus, according to an exemplary embodiment.

The display apparatus may transmit network information for connecting the mobile terminal and the display apparatus to the mobile terminal by using the other communication method instead of the short range wireless communication, in operation S300.

According to an exemplary embodiment, the network information may be information for the mobile terminal to connect to the display apparatus. For example, the network information may include information for pairing the mobile terminal and the display apparatus through the Bluetooth standard. Alternatively, the network information may include information for the mobile terminal to connect to the display apparatus through a wireless fidelity (Wi-Fi) direct. Alternatively, the network information may include an SSID of an access point for the mobile terminal to connect to the access point connected to the display apparatus.

According to an exemplary embodiment, the network information may include information about a list of communication methods performable by the display apparatus.

Then, the display apparatus may establish a communication linkage with the mobile terminal based on the transmitted network information, in operation S310. For example, the display apparatus and the mobile terminal may be paired through the Bluetooth standard or connected via Wi-Fi communication.

Then, in operation S320, the display apparatus may receive the information about the list of data stored in the mobile terminal from the mobile terminal through the communication linkage established in operation S310.

According to an exemplary embodiment, for example, the information about the list of data stored in the mobile terminal may include a list of contents, such as photographs and moving images, stored in the mobile terminal. Also, the information about the list of data stored in the mobile terminal may include a list of applications installed in the mobile terminal. The information about the list of data stored in the mobile terminal may include a list of other data stored in the mobile terminal, aside from above examples.

Also, according to an exemplary embodiment, the information about the list of data stored in the mobile terminal may include additional information about data included in the list. For example, the information about the list of data stored in the mobile terminal may include meta data including a thumbnail image of the data included in the list. Alternatively, the information about the list of data stored in the mobile terminal may include a stop image obtained from a frame buffer of the mobile terminal, if the data is a moving image. Alternatively, the information about the list of data stored in the mobile terminal may include an execution icon about an application included in the list.

Then, the display apparatus may display the received information about the list of data on the screen according to the location of the mobile terminal determined according to the process of FIG. 1, in operation S330.

According to an exemplary embodiment, the display apparatus may display the received information about the list of data according to the location of the mobile terminal determined in operation S120 of FIG. 1. For example, when the location of the mobile terminal is determined to be the coordinate value (x1, y1), the display apparatus may display the data based on an coordinate value (x1+a, y1) corresponding to the location that is moved by a predetermined pixel value from the coordinate value (x1, y1).
